Signo

Signo is a keyboard shortcuts manager. With it you can do dozens of actions on your computer just by pressing a special combination of keys.

Besides the classic keyboard shortcuts to open and close applications or shut down your computer, Signo also lets you assign snippets of text to paste into whatever application you have open at that time (MS Word or a browser, for example).

Other interesting actions let you minimize the use of RAM or take screenshots, all with a simple combination of keys.

Signo is a very useful application if you have the patience to learn all the keyboard shortcuts. This may be a bit difficult at first, but in the long run it's well worth it.
